I got married. How does the income tax return look? Update your marital status in the IRPF
Did you think: “I got married, how will my income tax return look?”? - and the practical answer is simple: update your marital status on your next tax return and check the impact on your assets and deductions.
When you get married, the IRS needs to know that your tax life has changed. This doesn't necessarily mean you'll pay more tax, but it can change who declares what and how assets are treated.
Atualizar o estado civil é um passo administrativo que evita inconsistências entre a base de dados da Receita e seus documentos. Se você mudou de nome no cartório, regularize o CPF e avise o banco. Fazer isso cedo evita dor de cabeça na hora de enviar o IRPF.
Marriage can affect what goes into your tax return: assets, joint accounts, income and dependents. Knowing the property regime you have chosen is essential - it defines whether an asset is yours, your spouse's or joint. Keep the certificate and the information: it will save you hours of time when filling in the form.
When and where you should change your marital status on your tax return
You must inform the change of marital status in the declaration for the year in which you got married. For example, if you got married in 2025, the tax return filed in 2026 must include your new marital status.
The change is made in the IRPF Program (download from Receita) or in the Receita Federal digital service when available. In the program, go to Taxpayer Data and update the Civil Status field; if there is a change of name, update the name/CPF.
If in doubt, an accountant can help you avoid time-consuming mistakes and fines. So as not to leave it to the last minute, check out up-to-date guidance on the deadline and submission at income tax 2025. See the Official IRPF information and deadlines.
What documents and spouse details you need to provide
Gather the main documents: marriage certificate, spouse's CPF, date of birth, property regime and, if available, partner's income reports. This data identifies the spouse and helps you decide where and how to declare income and assets.
- Marriage certificate (date and registry office)
- CPF and full name of spouse
- Date of birth
- Property regime chosen in the deed
- Income statements (salaries, pro-labour, investments) of the spouse, if any
Income reports include both fixed income and investments - see the practical guide on how to declare your income from fixed income and the articles on investment statement, variable income and guide to fixed income to find out where each item goes in the declaration.
If your spouse had no income, you can assess him or her as a dependent, where applicable. For instructions on the certificate, see How to obtain and validate a marriage certificate.
| Property regime | Main effect |
|---|---|
| Partial communion | Assets acquired after marriage are common |
| Universal communion | All assets are common, except those excluded by law |
| Total separation | Everyone keeps their own assets, with no communication of property |
| Final participation in the succession | Each manages his own assets, but shares the gains of marriage |
Quick tip: if you changed your name when you got married, update your CPF and banks before submitting your tax return. This avoids divergent data and rework.
Step by step to change marital status in the IRPF Program
Open IRPF Program → Taxpayer Data → change Marital Status to “Married” (or whichever applies) → fill in your spouse's details (name, CPF, date of birth and property regime) → enter his/her income reports, if any → check assets and income to avoid duplication → finish after reviewing the totals.
To avoid common mistakes when filling in the form, see also the content on how to avoid mistakes in your tax return.
Declaring marriage on the IRPF: choose between a joint or separate declaration
The question “I got married, how does the income tax return look?” comes up again when deciding whether to file jointly or separately. The joint return (including the spouse as a dependent) adds up income, deductions and dependents; the separate return treats each person as an individual taxpayer.
Sometimes joint reduces total tax; sometimes separate is better. Simulating both scenarios is essential.
The joint declaration requires agreement and can only be changed in different tax years, according to IRS rules. Keep receipts and do a simulation before submitting.

Advantages of joint declaration and when it pays off
The main advantage is to dilute tax rates and add up deductions. If one spouse has little income and the other has high deductions (health, education), filing jointly usually reduces the total tax and increases the chance of a refund. It also makes administration easier: a single declaration.
Factors to evaluate:
- Income difference between you
- Concentrated deductions (health, education)
- Possible change in tax payable or refund
Tip: do a simulation in the Receita program with both scenarios; see guidelines and deadlines at income tax 2025.
Why declaring separately can be better
Filing separately protects you from taking on the other's tax. If one spouse has tax risks, debts or undeclared income, keeping separate returns prevents the problem from affecting your tax.
It's also advantageous when you both have high incomes and few deductions - adding up salaries can push you into higher brackets.
How to decide between joint or separate based on your income
Compare scenarios: add up income and deductions for the joint return; then calculate each separate return and add up the taxes. Choose the option that results in the lowest total tax or highest refund. Simulation is decisive.
| Scenario | Best option |
|---|---|
| One spouse with a high income, the other with a low income and many deductions | Joint |
| Both with high incomes and few deductions | Separated |
| Tax risk or a spouse's debts | Separated |
| Medical/educational deductions concentrated in one | Joint |

Property regime and income tax: how the property regime affects you
The property regime defines who declares what on the IRPF. If a property belongs to the couple, both may have to declare their share; if it is individual, only the person listed as the owner declares. This alters the calculation of capital gains, the division of deductions and liability for debts.
Ask yourself: was the property bought before or after the marriage? In partial communion, everything acquired afterwards tends to belong to the couple; in total separation, each person keeps their own property.
If you're thinking “I got married, how does the income tax return look?”, check the ownership, date of purchase and registration on the documents.
In practice, this influences how much tax you pay when you sell an asset (capital gain), who adjusts the value in the tax return and how you register inheritances. E.g.: apartment bought by you before the marriage declared by you; car bought during the union needs to appear in the declaration of both, depending on the regime.
ATTENTION: always update the date of purchase, purchase price and names of the owners before sending the declaration - this avoids fines.
For issues related to transfer on death or gift, also evaluate succession planning in succession planning. See the Legal provisions on property regimes in the Civil Code.
Partial, universal communion and separation: what changes for your assets
In the partial communion regime, assets brought in before the marriage remain yours, but everything acquired during the union becomes common property (usually 50/50). In universal communion, practically everything is common, except for clauses. In total separation, each person only declares what is in their name.
Quick examples:
- You bought an apartment before you were married → normally yours (partial communion).
- You bought a car during your union → common property (partial/universal communion).
- Inheritance received by you can be excluded from the common lot depending on the regime and the prenuptial agreement.
| Regime | What happens to assets before marriage | Impact on the IRPF |
|---|---|---|
| Partial communion | Pre-marital property is yours; post-marital property is joint | Declare your assets; common assets distributed by fraction |
| Universal communion | Almost everything is common (except for clauses) | Both declare stakes in the property |
| Total separation | Everyone keeps their possessions | Everyone only declares what's in their name |
How property division and IRPF works when there is a sale or inheritance
When you sell a property, the capital gain is taxed on the difference between the sale and the adjusted cost. If the property belongs to the couple, the gain is apportioned according to their share. Each person calculates and declares their share of the gain.
In an inheritance, the person who receives the property enters the value of the property in the declaration for the year of receipt, based on the market value on the date of death. If the inheritance fell to both of you, you each include the fraction you received. Have deeds, inventory and receipts as proof and consider guidance on succession planning to reduce risks.
What to declare about assets you had before and those acquired after marriage
Declare the assets in your name according to the documents: what was yours before the marriage continues to be declared by you, unless there is an agreement to the contrary; assets acquired in the union that are shared need to appear proportionally in each person's declaration, with the correct acquisition value and date.
How to split married income and take advantage of tax deductions for couples
If you're asking, “I got married, how do I file my income tax return?”, the good news is that there are options: file jointly (a single return that adds up both your incomes) or separately (each of you files your own). What counts is who received the income - salary, rent, financial income - but in the joint declaration everything is added together. That's why simulating before submitting is essential. For a general overview of the rules and rates, see the Overview of income tax.
Choosing between joint or separate changes the result. Adding income together can push you into a higher bracket, but allows you to add deductions (medical expenses, education) and deduct more from the total tax. Filing separately is advantageous if one of you has little income and the other has a lot of deductions. The trick is to simulate both.
Keep receipts (receipts, reports, contracts) and define the ownership of properties and investments according to the documents. If the property is in both your names, divide the rent according to the registered share.
If organizing the accounts is complicated after the wedding, start with the basics with a plan of organization of accounts and then apply the principles of Family financial planning.
Rules for dividing salaries, rents and financial income
- Salary: declared by the person who received the payment.
- Rent: declare who owns the property; if the property belongs to both of you, divide the income in proportion to ownership.
- Financial income: follows the ownership of the account or investment.
Check your bank or brokerage firm's income statement - it usually shows the division or CPF of the beneficiary. In cases of inheritance, donation or transfer between spouses, keep contracts and notes. For details on how to declare different types of investment, see how to declare investments, variable income and fixed income guide.
Essential documents: payslip, bank statement, rental contract, payment receipts and proof of ownership.
How to add up or split medical, educational and other deductions
- Joint declaration: deductions are added together - medical expenses, educational expenses (with limits), court-ordered alimony and some donations go on the same form.
- Separate declaration: each person presents what they paid or what is on their CPF.
- Alimony: deductible by the payer only if there is a court decision or approved agreement; the recipient declares it as taxable income.
Assign the expense to the person who actually paid and run simulations to decide.
Practical example: you earn R$4,000 and your spouse R$2,000; together you receive R$1,000 in rent (50%/50%). When filing jointly, everything is added together (R$7,000). If you file separately, you each record your salaries and split the rent according to ownership.
| Situation | You | Spouse | Observation |
|---|---|---|---|
| Salary | R$ 4,000 | R$ 2,000 | Declare as received |
| Rent (property in both) | R$ 500 | R$ 500 | Split second ownership |
| Medical expenses paid by you | R$ 1,200 | — | Deductible from the payer's CPF |
| Joint declaration (total) | R$ 5,700 | — | Sum of all income and deductions |
- Gather documents, income statements and receipts.
- Simulate joint and separate declarations.
- Choose the option with the lowest tax and send it with organized receipts.

Income tax after marriage: dependents, pension and shared responsibility
A common question is: I got married, what does the income tax return look like? In practice, marriage allows you to choose who will declare income and expenses. You can include your spouse as a dependent - this brings together income and expenses in a single document. The decision affects the calculation basis, deductions and who is responsible for each receipt.
Alimony (court decision/approved agreement): deductible for those who pay and taxable for those who receive. Day-to-day expenses only generate tax benefits if they are deductible (education, health) with valid receipts and entered by the person who paid them.
Before deciding, make simulations: small differences can turn a refund into tax payable - or the other way around.
Who you include as a dependent after marriage and how this affects income tax
You can include your spouse as a dependent. In addition to your spouse, the following are accepted: children, stepchildren, parents, grandparents, incapacitated persons living under your maintenance. Including your spouse means that their income will be included in your tax return; be careful not to duplicate deductions - only one of you can use the same expenses.
How to declare alimony and expenses you share
- Alimony with court order/approved agreement: deductible by the payer; the recipient declares it as income. Inform the beneficiary's CPF.
- Voluntary payments without a legal agreement are not deductible.
- Medical/education expenses: deductible by those who actually paid, with valid receipts.
Useful documents:
- Proof of payment with CPF/CNPJ and name of beneficiary
- Court decision or approved agreement (for pension)
- Invoices or receipts for medical and school expenses
Tip: talk it over and do two simulations before deciding. If you want to improve your financial management and reduce tax surprises, read about financial planning for couples e Family financial planning.
How marriage can change your refund or tax liability
Getting married can increase or reduce your tax liability. Adding high incomes to a tax return can increase the tax rate; concentrating deductions in a single return can increase the refund. Rule of thumb: simulate both options and choose the one that generates the lowest tax liability or the highest refund. If the idea is to multiply the refund legally, see strategies in how to multiply restitution.
Couple's income tax - frequently asked questions: I Got Married How Is The Income Tax and practical solutions
The main rule: inform the change of marital status in the Revenue Program and choose the best way to declare. What counts is your marital status on December 31 of the base year. Inform the date of marriage and the property regime - these two pieces of information change how you present assets, income and deductions.
Couples don't make a single joint declaration with two names on the same form - the usual way is to include the spouse as a dependent (when advantageous) or to each declare separately. If you make a mistake, rectify the declaration - the sooner you do this, the less risk there is of you falling foul of the tax authorities.
Common questions and direct answers

How to correct your tax return if you forgot to declare your marriage or changed your property regime
Forgot to inform the marriage? Send a rectifying declaration through the Receita program. The rectification replaces the previous one; change marital status, property regime and adjust assets and income as necessary. Do this as soon as you notice the error.
Have you changed your property regime or shared assets and not updated them? Adjust the Assets and Rights sheet and the related income sheets. Document each change with contracts or deeds and contact an accountant if necessary.
| Situation | What to do | Observation |
|---|---|---|
| Married before 31/12 | Update marital status in the IRPF and inform property regime | You can include your spouse as a dependent or declare separately |
| Forgot to declare marriage | Send rectifying declaration | Rectifying as soon as possible reduces the risk of problems |
| Changed property regime | Adjusting Assets and Rights and documenting transfers | Have deeds/contracts handy for proof |

Final checklist to send your tax return without error and avoid a fine mesh
Before sending, check everything: date of marriage, property regime, income of both, deductions and documents. Do a quick cross-check: income x dependencies x assets.
- Check marital status on 31/12 and enter date of marriage.
- Confirm the property regime (prenuptial agreement, partial communion, total communion or separation).
- Check if your spouse will be included as a dependent and do a simulation.
- Update the Assets and Rights sheet with any transfers.
- Keep proof (certificates, contracts, receipts) and, if necessary, send a rectification.
If you have received or transferred funds via PIX, remember that some operations may need to be reported - see guidelines at PIX and tax return. And for those who need a practical guide to organizing documents before sending them, the article Organize your accounts at once helps a lot.
Please note: sending in the rectification form is not a shame - it's a responsibility. Better to correct now than explain later.
Conclusion
You got married - first step: update your marital status on your next tax return and regularize your CPF/name if it has changed. Gather certificates, income statements, contracts and receipts - these papers will save you headaches later.
Decide calmly whether to file jointly or separately. Simulate both. Simulation is your best friend to find out which option yields more refund or less tax to pay.
Remember: the property regime defines who declares what. A property bought before the marriage can remain yours; assets acquired during the union can be joint. Understand this before filing.
If you make a mistake, rectifying it is responsible and usually solves the problem. Small corrections today avoid big explanations later.
